To all whom it may concern:

Be it known that "I, MANUEL *HUMBER O PEREZ, a'citizen cf the Republic of Honduras, residing at San Pedro Sula, in the Department of "Cortez and Republic of Honduras, have invented new and useful Improvements in Phonograph-iltecord 'Repeaters, of which the .following is a specification.

This invention relates to a phonograph record-repeater, or device for 'attachmentito talking machines .whereby a record may be repeatedly played, the primary object of the invention'being'to provide a device of this character which is simple and inexpensive 'in construction, reliable and e'flicient in operation, and pleasing in shape and appearance was to constitute an ad- ,junct to the machine which may be made .as ornamental and attractive as desired,

according to the taste or fancy of the manu- .facturer [or of the person purchasing the sameffor use. v

A .further object-of the invention is to ,provide .a device of ,the stated character which may be-employedin connectioirwith all sizes and kinds of records and various makes of talking machines.

lTheinvention consists of the features of construction, combination .and arrangement .of ,parts, hereinafter .fully described ,and -claimed,: reference being bad to theaccom- ,panying drawing, in which:-

:Figure 1,,is,a topplanview of a phonograph .record repeater embodying my invention.

EIILgIhQPIQCClCEIl embodiment of my in- .vention, as herein .disclosed, .I provide a record repeater, comprising Ta member !1; in the tfo-rm of .a plate niadeof: she=et..metal or other sheet material suitable forv the purpose. Chis member -1 has va curved or arcuate .body portion 2v .terminatinguat ,one

.end intdiverging fiukes .or ww'ings, 3,.an'd l united ,by. a substantially -:V--shaped or triangular web 5 constituting a widened portion .of the fluke. At the opposite :end of the body portion 2 is curved or offset arm 6 defining a recess 7 designed to receive the needle or stylus "ofthe sound box of the phonograph when said needle is in starting position. "The body portion 2 is'o'f' substantially uniform width between its'end or extremity 8 fnom whichflthe arm 6 projects and thepointfi {from which the plate is widenedto form the wings or "fiukes 3 and 4'. :ancl'the intermediate web or expanded plate portion 5; Rails or guide ribs 10 and 11 extend upwardly from the plate-and form a 'guide 'groovefor guiding the a needle .so as to return :the sound" box or reproducer fromqthe final jgIOOVB or (finishing point ona -1tecord to rthe first groove or starting point on a record ii'or arepetitiono'f the composition to beplayed. These rails are relatively close-togetherzand extend substantially in parallel relation along the portionQ, of .the repeater, :providing a.fdelivery groove jl2' which" :is of substantially uniform .wi'dth except at 'the point where'it merges into ;'the recess 7, at which pointthe rails '10 are slightly flared to ,permit the needle "to move easily .into said recess'7 and engage the proper groove "in the record ,eigposed thereby. From the point. 9 the rails 10 and 'lldivergeas shown at 10 and; 11 and extendalon-g the widened portion 5 of the plate adjacent'tothe margins thereofand thence tofthe extremities of the flakes or ings 3 and A, forming guards to prevent displacement of the needle jfrom the repeater after it becomes initially engaged' therewith. The -'divergent portions ,10 andll ,o'f the rails are rsu'fl iciently spread to provide withthe edge portion 130i the web 5 a1fiaring mouth or entranceway to the gr'oove whichis sufficiently wide to engage and receive the needle, at any position which it may have .in thejfinalkgroove, ofa record of any,size and vto conduct the same to said groove for the return .of. the needle,to the starting.;p0int. As a result of the construction described, the {flaring initial point of jthe gnoovagradual-ly converges toward the return portion,12 of the groove, so that the needle will ibe conducted from any finishing pos i.tion ,Wliiclilitahay occupy at the com- ,pletion of the playingof fthe composition to the recess'7, at which point the needle an opening 17 for the reception of the spindle of the turntable of the machine, whereby the repeater is adapted to be fitted on said spindle. The block is also provided with a tubular friction grip member or ferrule 18 slotted to provide a series of spring grip fingers 19, which ferrule receives the spindle and which fingers are slightly pressed inwardly to frictionally engage the spindle under their spring pressure. This spring pressure is sufficient to adapt the repeater to be coupled to the spindle to rotate therewith and with the turntable of the phono graph at times, and also serves as a slip clutch which engages the spindle lightly enough to adapt the repeater to be held stationary while the record is rotating with the turntable in the playing of the composition. The head block 16 is adjustable in the slotted guideway of the yoke 15 so as to regulate its position with respect to, or distance from,

the recess 7, so that the repeatermay be adj usted with relation to the spindle and center of the record to dispose the recess 7 so as to overlie or register with the starting groove of a record of any kind. The yoke 15 is slit at one end to form the resilient yoke arms 20, and the free ends of these arms are normally slightly spread by their spring action and are formed with threaded half-bosses providing a divided screw 21 to receive an internally tapered cap nut 22, adapted to be adjusted outwardly and inwardly so as to permit the arms 20 to spread and release the head 16 when it is desired to adjust the same, and so as to adapt said yoke arms to be contracted to firmly and securely clamp the head in adjusted position. The arm 6 is provided with a sleeve 28 in which is fitted an adjustable stop rod 24: having an inner beveled end portion 25 and provided at its outer end with an adjusting knob 26. This rod 24 is provided with a spiral groove 27 to receive the point of a set screw 28 on the sleeve. When this set screw is slightly relaxed the rod 24, through its threaded connection therewith, may be adjusted inwardly and outwardly, and then by tightening the screw the rod may be firmly clamped in adjusted position. This rod is provided for engagement with the needle of the sound box to hold the repeater from rotation with the record while the composition is being played, and is adjustable to dispose its taperedend 25 to register with the final groove of a rec-' ord of any size or diameter, so as to release the repeater for rotation with the record when the needle reaches the final groove at the end of the composition.

In the operation of the device, the repeater is arranged to rest upon the record and its head 16 engaged with the turntable spindle, and the yoke 15 and stop rod 24 adjusted to dispose the recess 7 in line with the starting groove and the tapered end of the stop rod in line with the final groove of the record. The phonograph then being started into action, the repeater turns with the record until the needle engages the rod 24, which holds the repeater from rotation with the record fi l while the composition is being played, the spring fingers 19 of the clutch ferrule sliding on the spindle during this operation, and the repeater 1s so held from rotation by the sliding movement of the needle along the rod 2 1 until its end portion 25 is reached,

at which time the needle reaches the end of the record and passes beyond said portion 25, thus permitting the repeater to rotate with the record and turntable. A relative motion is thus established whereby, as the needle remains in a fixed position, the repeater is turned until some point of the edge 13 of the flaring guide plate 5 of the repeater engages the needle, which enters the flaring guideway of the return groove and, through the continued motion of the repeater, traverses the full length'of said groove and finally passes beyond the same into the recess 7, at which point the needle again engages the starting groove of the record and is in position to repeat the playing of the composition, whereupon a repetition of the above-described operation of the repeater occurs. Through the described action of the repeater, it'will be obvious that the needle may be returned to the starting point for the playing of the composition on the record any desired number of times, that the repeater may be adjusted to make the starting point any point in the groove of the record, for the repeater playing of the entire composition or any part thereof, and that the repeater may also be adjusted in an easy,

ready and convenient manner, for so regulating the action of the reproducer in connection with records of any size, from minimum to maximum.

The invention provides a simple, reliable and elficient type of repeating device which may be manufactured and sold at low cost, which may be applied, removed and adjusted for the purposes described with great ease and facility, and which may be used without.

injury to the record or parts of the phono graphic machine. thebody or plate l of the repeater is of unitary construction, together with the yoke 15, and employs in connection therewith only two additional independent parts, to wit, the

It will be observed that head 16 and stop rod 24, whereby a structure ofsimple form is provided which may be made as strong and rigid as desired and capable of being more or less roughly handled without liability of breakage or derangement. It will, of course, be understood that the device may be made as plain or as ornamental as desired, and it may be'provided on its underside with a layer or separate contact portions of felt or other similar material for engagement with the face of the record to prevent the same from being Scratched or otherwise marred.

Having thus fully described my invention, 1 claim:

l. A. phonograph record repeater including a member having a needle return guideway, a head engageable with the turnable spindle and having a resilient portion and a non-resilient portion, a split spring yoke on said member slidably receiving the head and engaging the non-resilient portion thereof, and means for contracting the yoke and causing it to bind against the non-resilient portion of the head.
